Description
Technical Field
The invention relates to a method for horizontal equipment to enter a frame, which is particularly suitable for large-scale and ultra-large-scale horizontal equipment.
Background
Horizontal equipment in a frame often cannot be directly hoisted in place by a crane like normal hoisting construction operation, other measures need to be taken to enable the horizontal equipment to enter the frame, and the following two measures are commonly used at present:
(1) a downward penetration method:
and (3) arranging hoisting holes above the equipment foundation layer (namely, all the frame floor plates above the equipment installation layer are provided with the hoisting holes), hoisting the horizontal equipment to the installation layer from the hoisting holes, and directly entering the frame. The disadvantage of this measure is that the space reservation of the floor is required, which not only increases the design difficulty, but also affects the construction progress of the frame.
(2) An electric hoist access method:
and (3) hoisting the horizontal equipment to the horizontal equipment mounting layer opening of the frame by using a crane, hoisting the horizontal equipment into one end of the frame by using an electric hoist, and gradually hoisting the horizontal equipment into the frame (as shown in figures 6-8).
